Datatable动态导出Excel，IExporterHeaderFilter设置禁用表头筛选器无效

DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("ProductCode", typeof(string)));
dt.Columns.Add(new DataColumn("ProductName", typeof(string)));
dt.Columns.Add(new DataColumn("Quantity", typeof(string)));
for (int i = 0; i < 10; i++)
{
var row = dt.NewRow();
row["ProductCode"] = "ProductCode" + i.ToString();
row["ProductName"] = "ProductName" + i.ToString();
row["Quantity"] = "Quantity" + i.ToString();
dt.Rows.Add(row);
}
IExcelExporter excelExporter = new ExcelExporter();
//设置IExporterHeaderFilter为null无效
var res = await excelExporter.ExportAsByteArray(dt,null);
return new FileStreamResult(new MemoryStream(res), "application/octet-stream")
{
FileDownloadName = $"{DateTime.Now.ToString("yyyyMMdd")}.xlsx"
};

还是有筛选器
